I just got the CJ79 34" Monitor. I connected the given Thunderbolt 3 cable from the monitor to my Laptop's USB-C port and the video display shows up fine. However, when I connect peripherals like a wireless mouse to the Monitor's USB-A ports, the monitor does not act as a USB hub as advertised, even though the 'USB Hub' mode is on
Just to doublecheck, have you updated your software recently?
I recommend giving the device an update.
Hi Samsung Larry,
I checked the manual on how to do the software update. It instructed me to unsert a 'USB Disk'. My monitor didn't come with any USB Disk, and there is no other information on what is is or alternate means to do the software update.
Are using a USB2.0 wireless mouse? Also to update the firmware you would need a USB 2.0 Stick and would need to download the firmware version manually and then manually install it.
You can use this link to find the new version: https://www.samsung.com/us/support/owners/product/thunderbolt-3-ultra-wide-screen-j791
I tried to download the firmware, but I could only find the file 'C34J79xWT.exe' at the link. The manual (screenshot below) says that for the upgrade to work, I need to ahave a file that has the extension '.bin' Please advise. Yes the mouse is USB 2.0
My apologies for the confusion, did you run the .exe from the link it will be the drivers for the monitor.
Yes, I tried several times. Still no success.
I got the screen below and made a selection with the "Thunderbolt" option. I got a notification that the manual driver was installed, but my peripherals still do not work.
Have you tried any other mouse to the monitor? Also, is the drivers installed on the computer for the mouse? And does the mouse work when connected directly to the laptop?
